Sound is a physical entity, unlike noise which is the perception of sound. Sound is an high pressure wave front through a medium (such as air, or a liquid such as water, or a solid), wherein the wave front is followed by a reciprocal pressure differential behind it. Sound is produced when something disturbs the medium and sets in motion the molecules in the medium. Frequently, (no pun intended) the wave front/reciprocal entity occurs as an oscillating wave, wherein there are a series of wave fronts (peaks in pressure), followed by wave valleys (lower pressure). The relative height of the peak translates to how much energy is in the wave (how great is the pressure), and the closeness of peak to peak (spatially and temporally) indicates the pitch. Noise, is not a physical entity, but is the mental perception of the physiological response to sound. A wave front is converted from mechanical energy in our ear into an electrical impulse in the brain that analyzes the wave information. The interpretation of the wave front is subjective and the brain may interpret the wave signature as speech, music, clapping, gunshot, hum, etc.
Vibrations would make the air layers in contact with it to move forward and backward. So longitudinal waves are produced in the air medium. This wave traverses in the material medium and as it reaches the ear drum the same to and fro motion occurs and it is sensed as sound.
A vibration or movement in an object pushes the air into little waves that repeat very quickly. The waves reach your ear and vibrate the eardrum, which moves through different parts of your ear, (that's another question) and your brain interprets the vibration as sounds.

Sound IS vibration. When solid objects vibrate (such as a loudspeaker), the object vibrates the air, and each vibrating air molecule causes the next molecule over to vibrate as well. When the vibrating air makes the eardrum vibrate, we "hear" the vibrations.
When solid objects vibrate in a vacuum, there is no air to carry the vibrations, so there is no sound. But if two astronauts touch their helmets together, the vibrations go from mouth to air to helmet to helmet to air to ear, and they can hear each other.
sound can be produced by stomping and your pitch can be changed with helium sorry spelled helium wrong
A fiddle is a stringed instrument. The sound is produced by plucking strings. The pitch is determined with the fret board.
The sound waves produced by a whistle are at a higher frequency than that of a beaten drum, causing the sound registered by human ears to be at a "higher pitch". Dog whistles can only be heard by dogs because the sound waves produced are at such a high frequency, human ears cannot detect them.
By air splitting.
It produced by the sounds.
A sound is produced in a wind instrument when a column of air vibrates inside a tube.A sound is produced when a column of air vibrates inside a tube.

sound is produced in veena by vibrating the strings of it
The smoke is produced slightly before the sound. Smoke is produced by the ignition of the propellant in the round. The sound is produced when the bullet passes through the sound barrier.

which kind of sound is produced by sound waves with peaks that are very close together?
A sound is produced when a metal blade called a tangent strikes the string.
voice*
sound produced through the vibrating object .
Sound is produced. Vocal cords vibrate and produce sound.
It's the wings that make the sound
